summary:
Lean Out: The Struggle for Gender Equality in Tech and Start-Up Culture is a 2015 book written by Elissa Shevinsky, an information security entrepreneur and feminist. Shevinsky wrote it in response to Sheryl Sandberg's Lean In, a book often criticized by feminists as being unrealistic in its expectations on women. == Reactions == The book was listed by Inc. Magazine as one of the 100 best business books of 2015. Newspaper reviews have been nearly universal in their approbation of Shevinsky's work, with the Los Angeles Times saying "the book is not just directed at women who might want to opt out of the rat race and start their own thing. This book is packed with stories — and statistics — that should give anyone in tech management pause." At least one review notes that "the essays end up varying widely in quality, radical message, level of editing, and scope. Among incisive critiques of nerd sociology and important stories of micro and macro aggressions, there are also far too many unnecessarily long resumes and capitalist self-help manuals in the book." == References ==

summary:
The Matilda effect is a bias against acknowledging the achievements of women scientists and inventors, whose work is consequently attributed to their male colleagues. This phenomenon was first described by suffragist and abolitionist Matilda Joslyn Gage (1826–1898) in her essay, "Woman as Inventor" (first published as a tract in 1870 and later published in the North American Review, retitled "Woman as an Inventor", in 1883). The term Matilda effect was coined in 1993 by science historian Margaret W. Rossiter. Rossiter provides several examples of this effect. Trotula (Trota of Salerno), a 12th-century Italian woman physician, wrote books which, after her death, were attributed to male authors. Nineteenth- and twentieth-century cases illustrating the Matilda effect include those of Nettie Stevens, Lise Meitner, Marietta Blau, Rosalind Franklin, and Jocelyn Bell Burnell. The Matilda effect was compared to the Matthew effect, whereby an eminent scientist often gets more credit than a comparatively unknown researcher, even if their work is shared or similar. == Research == In 2012, Marieke van den Brink and Yvonne Benschop from Radboud University Nijmegen showed that in the Netherlands the sex of professorship candidates influences the evaluation made of them. Similar cases are described by Andrea Cerroni and Zenia

summary:
In 1934, the Nobel Prize in Physiology or Medicine was awarded to George Whipple, George Richards Minot, and William P. Murphy. They felt their female co-worker, Frieda Robscheit-Robbins, was excluded on grounds of her sex. Whipple, however, shared the prize money with her as he felt she deserved the Nobel as well, since she was co-author of almost all of Whipple's publications. In 1944 the Nobel Prize in Chemistry was given to Otto Hahn as the sole recipient. Lise Meitner had worked with Hahn and had laid the theoretical foundations for nuclear fission (she coined the term nuclear fission). Meitner was not recognized by the Nobel Prize Committee, partly due to her gender and partly due to her persecuted Jewish identity in Nazi Germany. She was affected by the Law for the Restoration of the Professional Civil Service, which prohibited Jews from holding government-related positions, including in research. Initially, her Austrian citizenship shielded her from persecution, but she fled Germany after Hitler's annexation of Austria in 1938. In 1950, Cecil Powell received the Nobel Prize in Physics for his development of the photographic method of studying nuclear processes and for the resulting discovery of the pion (pi-meson).

summary:
The Nelson Diversity Surveys (NDS) are a collection of data sets that quantify the representation of women and minorities among professors, by science and engineering discipline, at research universities. They consist of four data sets compiled by Donna Nelson, Professor of Chemistry at the University of Oklahoma during fiscal years (FY) 2002, 2005, 2007, and 2012 through the Diversity in Science Association. These surveys were each complete populations, rather than samples. Consequently, the Surveys quantified characteristics of the faculty which had never been revealed previously, drawing great attention from women and minorities. Furthermore, the Surveys initially came at a time when these underrepresented groups were becoming concerned and vocal about perceived inequities in academia. At the time the surveys were initiated, the MIT Study of 1999, expressing the concerns of women scientists (including Nancy Hopkins), had just been issued, and underrepresented minority (URM) science faculty noticed URM students increase among PhD recipients without a corresponding increase among recently hired professors. Data sets like the NDS, along with similar research available through the NSF, allowed URM faculty to track the progress of diversity efforts in the STEM fields. As noted by the Women's Institute for Policy Research, progress has been slow

summary:
While STEM (science, technology, engineering and mathematics) fields all over the world are dominated by men, the number of Pakistani women in 'STEM' is low due to one of the highest gender gaps in STEM fields. However, over the time, some Pakistani women have emerged as scientists in fields like physics, biology and computer sciences. == Gender gap in Pakistan == Pakistan has one of the highest gender gaps in the world, and it is the third least performer in gender parity according to a report published by World Economic Forum in 2020. The low literacy rate of women in Pakistan, despite women making almost half the population, is one of the factors in a high gender gap in STEM fields. This literacy rate is even lower in science and technology. === Facts === According to UNESCO, among students enrolled in bachelor's degrees, 47% are women while 53% are men. The number of women pursuing doctoral studies is only 36%, while the percentage of men is 64%. There is also a significant gender gap in research sector, with women making only 34% of researchers. Among students in universities, the field of natural sciences is reported to have only 40% women

summary:
Films have portrayed professional women in science, technology, engineering, and mathematics (STEM) fields in various ways throughout film history. == Overview == The study of female characters in film began with movements from the 1960s and 1970s in the form of second-wave feminism, the rise of independent films, and the beginning of academic film studies. Some films promote certain socially defined female stereotypical archetypes that often combine job stereotypes with gender stereotypes. The use of these stereotypes in film has been suggested to contribute to a questionable portrayal of women, especially revolving around themes of violence, sexuality, objectification, and subordination. == Examples of female scientists in film == === Early 20th century === The presentation of women as scientists on film goes back to the early days of cinema. The first known presentation may be 1929's Woman in the Moon. Written by Thea von Harbou and directed by Fritz Lang, the film follows a group of Germans as they travel to the Moon. The group includes Friede Velten, an assistant on the trip, who chooses between two potential husbands and ultimately decides to stay on the Moon and live a new life there. It would take almost ten years before

=== Arrival (2016) === The 2016 film Arrival revolves around the character of linguist Dr. Louise Banks, played by Amy Adams, who facilitates the very first instance of human communicative contact with an alien population. The film makes an obvious effort at employing a feminist theme, primarily through the way the backstory shapes Dr. Banks and frames her as an accomplished professional and mother. === Hidden Figures === Hidden Figures was released in 2016 and told the true story of three female African-American mathematicians, Katherine Johnson, Dorothy Vaughan and Mary Jackson (engineer) who worked at NASA during the Space Race. === Black Panther (2018) === The critically acclaimed film Black Panther features Princess Shuri, a young, Black, female character who excels in the STEM field as an intelligent and creative technology whiz and inventor. Portrayed by Letitia Wright, Princess Shuri is the younger sister of T'Challa (Chadwick Boseman), the eventual king of Wakanda, and the mastermind behind harnessing the power of vibranium, specifically in the creation of the Black Panther suit. The Marvel Cinematic Universe has portrayed over 60 fictional scientists, about a quarter of them being women, including computer expert Dr Helen Cho, biologist Dr Maya Hensen and biochemist

summary:
=== The Lonely Heroine === This type of woman scientist is intelligent, attractive, and somewhat independent. Flicker says that she "has appropriated some male traits," such as losing herself in her work. She is both sexual and smart, and she manages to exhibit both qualities in the film. Despite this, she is still subordinate to the men on her team, and depends on them and their work to gain respect. She is the most progressive of the woman scientist types, but she lacks her own form of independence and still must rely on a sexual relationship with a man to be seen as someone. The "lonely heroine" type is best seen in Jodie Foster's portrayal of Elleonore Arroway in the film Contact. == Objectification of women in film == Flicker argues that women are often pigeonholed into these six limiting roles when written in films. Each of these roles places the female scientist character on the sidelines, and does not allow her to be on the same level as her male counterpart(s). Although the women in these roles are educated, and often just as educated as the men on their team, they are used primarily as assistants and sexual characters.

== Opposing views == Noël Carroll references Mulvey's pivotal paper on psychoanalysis and visual pleasure in his writing, and plays devil's advocate to her claim that women are the only subjects of gaze. Carroll acknowledges and agrees with Mulvey's assessment that women in film are strategically placed for the male gaze despite the role of their actual character. Carroll states, "Women in Hollywood film are staged and blocked for male erotic contemplation and pleasure." However, Carroll adds that men in films are also strategically placed for the purpose of pleasure. He cites such examples as Sylvester Stallone and Arnold Schwarzenegger, big bodybuilding actors "whose scenes are blocked and staged precisely to afford spectacles of bulging pectorals and other parts." Similarly to actresses, male actors are also heralded for their facial attractiveness and are sometimes lauded exclusively for being attractive. As an example, Carroll offers Leslie Howard, a male actor who appeared in Of Human Bondage and Gone With the Wind, who was highly successful in the industry despite being "staggeringly ineffectual." According to Carroll, being subject to the erotic gaze of the audience is not an exclusively female burden; rather, both sexes fall prey to Hollywood camera angles that best

summary:
According to the National Science Foundation (NSF), women and racial minorities are underrepresented in science, technology, engineering, and mathematics (STEM). Scholars, governments, and scientific organizations from around the world have noted a variety of explanations contributing to this lack of racial diversity, including higher levels of discrimination, implicit bias, microaggressions, chilly climate, lack of role models and mentors, and less academic preparation. == Race imbalance in STEM in the United States == Racial minorities, with the exception of Asian Americans, are underrepresented through every stage of the STEM pipeline. === Education and degree attainment === Racial disparities in high school completion are a prominent reason for racial imbalances in STEM fields. While only 1.8% of Asian and 4.1% of White students drop out of high school, 5.6% of Black, 7.7% of Hispanic, 8.0% of Pacific Islander, and 9.6% of American Indian/Alaskan Native students drop out of high school. Among those that graduate high school, 67% of Whites, 62% of Blacks, and 69% of Hispanics enroll in a “degree granting college.” While there is no measurable difference in college enrollment of White, Black, and Hispanic STEM students, only 15% of Black students who initially enrolled in a STEM major received a

summary:
=== Microaggressions === People of color and underrepresented minority groups in science, technology, engineering and math are more likely than whites to experience racial microaggressions. Studies show racial microaggressions that occur on college campus weaken students sense of belonging, make it difficult to form relationships with faculty, and contribute to less cultural alignment with STEM. At predominantly white institutions (PWI) environmental microaggressions are common in shared laboratory spaces among students and during meetings with faculty and advisors. Black female students are especially likely to feel alienated and isolated from their peers in STEM departments. === Implicit bias === Research on implicit bias demonstrates that as early as preschool teachers are likely to hold implicit bias against students of color, especially Black boys. While Black children make up 19% of preschool enrollment, they account for about half of preschool suspension. Implicit biases among teachers, faculty, and colleagues makes it more difficult for students of color to form relationships, network with professionals in their fields, and find valuable mentors. Judgments placed upon people of color based on implicit biases are incredibly damaging and contribute to stereotype threat, which affects their overall performances. For instance, Black women are often assumed to be under-qualified

summary:
=== Protective factors === Those in STEM fields have recognized that there is an extensive history of poor representation of women and people of color in STEM and are working to close the gap. Addressing this issue requires a coherent and sustained effort across multiple fronts. Many would argue that single intervention does not work, but that sustainable and strategic reform in education, work place, and within our communities would put our theory in to practice. Transforming our perception of STEM in the early education years for students of color necessitates celebration of the distinct contribution that women and people of color bring to science, technology, engineering, and mathematics. === Teachers === While many teachers are highly dedicated to reducing the race gap and actively striving to create equal opportunities in their classrooms, they can actually contribute to the STEM race gap. Researchers suggest that a teacher's attitude toward's their own profession will predict their attitude over STEM education, with emotional readiness, cognitive readiness and self-efficacy all playing part mediating roles. Meaning teachers who have zero confidence in STEM or under prepared are more likely to teach it incorrectly, which could be detrimental to students of color who already face

summary:
Women Are Boring is an online publication featuring research by women. It aims to improve the visibility of women researchers, in response to the poor representation of discoveries by women in media outlets that quote or cover academic research. Women Are Boring is primarily a platform for women to post summaries or synopses of research that they have published in a different venue, on any topic. == History and motivation == Grace McDermott and Catherine Connolly founded the publication while they were PhD students at Dublin City University in May of 2016. McDermott and Connolly attributed their decision to found Women Are Boring to the under-representation of women in media, and particularly the underrepresentation of women scholars in news about research. They were specifically motivated by a study by The Global Media Monitoring Project which concluded that "only 24% of the persons heard, read about or seen in news media are women", and that only 28% of the sources cited in Irish news media were women, with only a very small proportion of those in expert roles like scientific or academic sources. McDermott and Connolly have noted the contrast between the dearth of women researchers in popular media and the

Women at NASA highlights the scientists, engineers, managers, flight controllers, and astronauts whose work has shaped the United States civil space program from the National Advisory Committee for Aeronautics era to the present, with their roles and contributions varying significantly over time. Women entered NACA in the 1920s as technical specialists, including physicist Pearl I. Young, the first woman hired as a professional employee at Langley Memorial Aeronautical Laboratory in 1922, and expanded in the 1940s to large pools of "human computers" who performed critical aeronautical and astronautical calculations by hand at Langley and other facilities. Over time those roles widened into engineering, science leadership, flight operations, and spaceflight, culminating in major program firsts and center leadership positions across the agency. Throughout the 1930s to the present, more women joined the NASA teams not only at Langley Memorial, but at the Jet Propulsion Laboratory, the Glenn Research Center, and other numerous NASA sites throughout the United States.[2] As the space program has grown, women have advanced into many roles, including astronauts. NASA's first six female astronaut candidates were selected in 1978 at Johnson Space Center, followed by decades of mission milestones and leadership appointments across multiple centers. By the 2010s

On June 18, 1983, Sally Ride became the first American woman astronaut to travel to space. More than a year later, Judith Resnik flew aboard Space Shuttle Discovery and became the second American woman in space. Kathryn D. Sullivan became the first American woman to perform a spacewalk in 1984. In 1988, Ellen Ochoa joined NASA and became the first Hispanic woman astronaut. Ochoa completed four space shuttle missions aboard Discovery and Atlantis, accumulating nearly 1,000 hours in space. In 1985, Shannon Lucid completed her first spaceflight and by the end of her career had spent 188 days in space. Lucid held the American record for most cumulative days in space until 2002. In the 1986 Space Shuttle Challenger disaster two women died: Christa McAuliffe, who would have been the first teacher in space, and Judith Resnik, the second American woman to fly in space. === 1990s === By the 1990s, NASA had expanded its research into the physiological effects of spaceflight on women's bodies. Carolyn Huntoon delivered a keynote address in 1994 at the 2nd Annual Women's Health and Space Luncheon, highlighting NASA's previously unrecognized contributions to women's health research.

The Women in Space Program (launched December 20, 1959) was a revived version of the Women in Space Earliest program that had been cancelled in November 1959. Like the program for men, this required candidate testing. However, the testing parameters were modified to accommodate women. In the screening phase, men were required to be degree-holding jet pilots who had attended military test pilot school and had a minimum of 1,500 hours of flying time. Since women were excluded from these opportunities, the screening criteria shifted to women with commercial pilot licenses, particularly those who served as flight instructors. Cobb, who underwent testing first, became the leader of the FLATs (Fellow Lady Astronaut Trainees) along with 12 other women, totaling 13 women (hence the media designation "Mercury 13"). Although Cobb was assigned as a NASA consultant and continued the testing process, women were still not trained as astronauts. During the examinations, some scientists believed that women demonstrated advantages over men for space missions. For example, women's internal organs were thought to be better suited to withstand radiation and vibrations. Due to women's generally smaller size, spacecraft and flights would be less expensive if women were used as astronauts. However, testing for

summary:
Women in archaeology is an aspect of the history of archaeology and the topic of women in science more generally. In the nineteenth century women were discouraged from pursuing interests in archaeology, however throughout the twentieth century participation and recognition of expertise increased. However women in archaeology face discrimination based on their gender and many face harassment in the workplace. == History == As a professional field of study, archaeology was initially established as an academic discipline in the nineteenth century and typically developed from people engaged in the study of antiquities. Prior to the Victorian era, women in Canada, the United Kingdom and the United States were rarely engaged in professional archaeology (though at this time, archaeology was not so much a profession as the practice of wealthy individuals, with workers paid to undertake the digging). Participation by women in the field was discouraged, both by men and societal pressure, as the occupation masculinized the accepted view of women as homemakers and nurturers. Even after they began to enter the field, the reluctance of male colleagues to accept them in fieldwork, led many women to choose roles outside of academia, seeking positions in museums or in cultural preservation associations.

summary:
=== Glass ceiling === Statistics show that women experience a glass ceiling in academic archaeology. Sue Hamilton, the director of the UCL Institute of Archaeology, noted that 60–70% of the institute's undergraduate and postgraduate students were women, as were the majority of its postdoctoral researchers. However, the proportion of women amongst permanent academic staff has never been more than 31%. Women are progressively further under-represented in each academic rank at the institute: 38% of lecturers are female, 41% of senior lecturers, 17% of readers, and just 11% of professors. A 2016 study found a similar pattern in Australian universities. Whilst 41% of academic archaeologists were women, there was an imbalance in female representation in research fellowships (67%) compared to higher-ranked lecturing posts (31%). This study identified a "two-tiered" glass ceiling: women were less likely to obtain permanent tenure-track positions, and those that did also found it more difficult to advance to senior ranks. In 1994, around 15% of the archaeologists working in the top 30 academic institutions for the field were women. On the other hand, it was within academic archaeology that women first broke the glass ceiling at a number of British universities. Dorothy Garrod was the first woman

summary:
Women in Cell Biology (WCIB) is a subcommittee of the American Society for Cell Biology (ASCB) created to promote women in cell biology and present awards. == History == A group of women were unhappy with the lack of recognition in ASCB. In 1971, Virginia Walbot gathered a group of women to meet at the annual ASCB meetings and WICB began. The goal was to provide a space for women to talk and network with other women in the field, learn about job opportunities, and promote women in academia. Newsletters were distributed containing job listings and news of powerful women in biology. Originally, WICB was not accepted by ASCB; the newsletter was not funded and later discontinued in the 1970s. WICB was established as a standing committee within ASCB in 1993. The formation of the committee correlates with increased women representation at the annual meeting. Between 1967-1977, there was only one woman speaker at the annual meeting; between 1990-1999, 21% of speakers were women. These numbers increased to parity with men by 2020 with equal numbers as speakers and as award recipients. == Activities == Currently, WICB meets annually at ASCB meetings and has a column in the ASCB newsletter.

summary:
The Working Group on Women in Physics of the International Union of Pure and Applied Physics (IUPAP) was formed by resolution of the Atlanta IUPAP General Assembly in 1999. The mandate of the group is: to survey the present situation and report to the council and the liaison committees and to suggest means to improve the situation for women in physics. To carry out this charge the Working Group has, among other things, organized six International Conferences (Paris, France, in 2002, Rio de Janeiro, Brazil, in 2005, Seoul, South Korea, in 2008, Stellenbosch, South Africa, in 2011, Waterloo, Canada, in 2014 and Birmingham, UK, in 2017) gathering teams from more than 60 countries that collected data on their local situation of women in physics. It also promoted and collaborated with the elaboration of a global survey of physicists that was carried on by the Statistical Research Center of the American Institute of Physics. The IUPAP Working Group is currently involved in the elaboration of a new survey that will include other natural sciences and mathematics within the framework of the Gender Gap in Science Project funded by the International Council for Science, ICSU. == References == == External links ==

summary:
The Betz mystery sphere is a metal sphere with an approximate diameter of 8 inches (20 cm) weighing nearly 22 pounds (10 kg) uncovered in 1974 by a family in Florida. == Background == On March 27, 1974, the Betz family investigated a small brush fire near their residence on Fort George Island, Florida. The family of three, Antoine, Jerri, and son Terry, came across a small metal sphere the size of a bowling ball. Their first thought was the sphere had been a cannonball left from New World conquistadors. They decided to take the sphere back to their house. Several days later, Terry was playing the guitar in their home. The sphere seemed to react to the sound of the guitar. It made a throbbing noise. Later, the sphere was noticed to roll on its own and even stop on its own and change direction. Terry started doing experiments with the sphere. He noticed the sphere would reverberate when hit with a hammer. He also found the sphere would move after being shaken and placed on the ground. The Betzes reported that the sphere moved on its own several times, and that it would follow people around the house

summary:
The CERN ritual hoax is a found footage video that depicts a faux occult ritual occurring in the grounds of CERN, the intergovernmental organization that operates the largest particle physics laboratory in the world. The video became popular in August 2016 and shows several people dressed in black cloaks surrounding a statue of the Hindu deity Shiva and apparently performing a human sacrifice, in apparent mockery of existing conspiracy theories which suggest that CERN aims to use the Large Hadron Collider to create a portal to hell, summon the antichrist, or destroy the universe. The video ended with the person filming crying out and running away. == Reactions == A CERN spokesperson stated that the video was a prank and that no one was actually harmed. CERN stated in its FAQ that the video was "fiction" and the actions were outside its professional guidelines and without any official permission. CERN stated that it "doesn't tolerate this kind of spoof" and that it can "give rise to misunderstandings about the scientific nature of our work". == References ==

summary:
The chemtrail conspiracy theory is the erroneous belief that long-lasting condensation trails left in the sky by high-flying aircraft are actually "chemtrails" consisting of chemical or biological agents, sprayed for nefarious purposes undisclosed to the general public. Believers in this conspiracy theory say that while normal contrails dissipate relatively quickly, contrails that linger must contain additional substances. Those who subscribe to the theory speculate that the purpose of the chemical release may be solar radiation management, weather modification, psychological manipulation, human population control, biological or chemical warfare, or testing of biological or chemical agents on a population, and that the trails are causing respiratory illnesses and other health problems. Chemtrail conspiracy theories emerged in the late 1990s after publication of a 1996 United States Air Force (USAF) report on weather modification, with the Air Force accused of secretly spraying substances via aircraft. The theories spread through internet forums and were popularised by radio host Art Bell from 1999. Chemtrails have been dismissed by the scientific community. There is no evidence that purported chemtrails differ from normal water-based contrails routinely left by high-flying aircraft under certain atmospheric conditions. Proponents have tried to prove that chemical spraying occurs, but their analyses have

summary:
Proponents of the chemtrail conspiracy theory say that chemtrails can be distinguished from contrails by their long duration, asserting that the chemtrails are those trails left by aircraft that persist for as much as a half-day or transform into cirrus-like clouds. The proponents claim that after 1995, contrails had a different chemical composition and lasted a lot longer in the sky; proponents fail to acknowledge evidence of long-lasting contrails shown in World War II–era photographs. Proponents characterize contrails as streams that persist for hours and that, with their criss-cross, grid-like, or parallel stripe patterns, eventually blend to form large clouds. Proponents view the presence of visible color spectra in the streams, unusual concentrations of sky tracks in a single area, or lingering tracks left by unmarked or military airplanes flying atypical altitudes or locations as markers of chemtrails. Photographs of barrels installed in the passenger space of an aircraft for flight test purposes have been claimed to show aerosol dispersion systems. The barrels' actual purpose is to simulate the weight of passengers or cargo. The barrels are filled with water, and the water can be pumped from barrel to barrel to test different centers of gravity while the aircraft is

=== Incidents === In 2001, in response to requests from constituents, U.S. Representative Dennis Kucinich introduced (but did not author) H.R. 2977 (107th), the Space Preservation Act of 2001, which would have permanently prohibited basing weapons in space, listing chemtrails as one of a number of "exotic weapons" that would be banned. Proponents have interpreted this explicit reference to chemtrails as official government acknowledgment of their existence. Skeptics noted that the bill in question also mentions "extraterrestrial weapons" and "environmental, climate, or tectonic weapons". The bill received an unfavorable evaluation from the United States Department of Defense and died in committee, with no mention of chemtrails appearing in the text of any of Kucinich's three subsequent failed attempts to enact a Space Preservation Act. In 2003, in a response to a petition by concerned Canadian citizens that "chemicals used in aerial sprayings are adversely affecting the health of Canadians", the Government House Leader responded: "There is no substantiated evidence, scientific or otherwise, to support the allegation that there is high altitude spraying conducted in Canadian airspace. The term 'chemtrails' is a popularised expression, and there is no scientific evidence to support their existence." The House leader added, "it is our

summary:
The dead Internet theory is a conspiracy theory that asserts that, since around 2016, the Internet has consisted primarily of bot activity and automated content manipulated by algorithmic curation. This alleged coordinated effort aims to control the population and reduce genuine human interaction. Supporters of the theory claim that social bots were deliberately created to manipulate algorithms and enhance search results to influence consumers. Some proponents also accuse government agencies of using bots to shape public perception and opinions. The dead Internet theory gained renewed interest following the AI boom that began in the 2020s, with large language model (LLM) chatbots and text-to-image models emerging as technologies that could theoretically drown out human-authored content on the web. In the time since, social media sites have seen a measured increase in bot activity, such as algorithmic feeds displaying low-quality AI slop at the expense of user-generated content. Despite there being no evidence of a conspiracy, commentators have linked some aspects of the dead Internet theory to this rise in generative content across social media. Sources see the theory as having some amount of truth behind it, or as offering a potentially realistic prediction of the Internet's future. One source uses the

=== "Leaner" dead Internet theory === In a 2026 article, Hal Berghel discussed what he called a "Leaner" dead Internet Theory, "stripped of paranoia, prejudice, politics and polemic." In this discussion, Berghel points to the 2025 publication in AI & Society by Yoshija Walter, and lists algorithmic generated content, Generative AI byproducts, the difficulty for some people to distingusish between this and human generated content, and the resulting mistrust and misinformation as the core of the dead Internet theory. Berghel laments that conspiracy theorists take these phenomena and to make implausible claims, while arguing that core criticisms should not be dismissed. == Expert view == Caroline Busta, founder of the media platform New Models, was quoted in a 2021 article in The Atlantic calling much of the dead Internet theory a "paranoid fantasy", even if there are legitimate criticisms involving bot traffic and the integrity of the Internet, but she said she does agree with the "overarching idea". A 2021 Ouest-France article, which heavily referenced the 2021 article in The Atlantic, went on to compare the dead Internet theory to flat Earth and COVID-19 conspiracy theories. The article stated that even though bots do produce online content, the dead Internet

=== Bot traffic === In 2016, the security firm Imperva released a report on bot traffic after examining over 16.7 billion visits to 100,000 randomly selected domains, and found that automated programs were responsible for 52% of web traffic. This report has been used as evidence in reports on the dead Internet theory. Imperva's report for 2023 found that 49.6% of Internet traffic was automated, a 2% rise from 2022, which was partly attributed to artificial intelligence models scraping the web for training content. A 2023 policy paper from the Institutul Diplomatic Român cited this increase in bot traffic as the basis for the dead Internet theory. === Large language models === Generative pre-trained transformers (GPTs) are a class of large language models (LLMs) that employ artificial neural networks to produce human-like content. The first of these to be well known was developed by OpenAI. These models have created significant controversy. For example, Timothy Shoup of the Copenhagen Institute for Futures Studies said in 2022, "in the scenario where GPT-3 'gets loose', the Internet would be completely unrecognizable". He predicted that in such a scenario, 99% to 99.9% of content online might be AI-generated by 2025 to 2030. These predictions

In a 2024 article in Fast Company, journalist Michael Grothaus linked this and other AI-generated content on social media to the dead Internet theory. In this article, he referred to the content as "AI slime". === YouTube === YouTube is susceptible to fake views generated by computers, not human users, and fake views were so prevalent that some engineers were concerned YouTube's algorithm for detecting them would begin to treat the fake views as default and start misclassifying real ones. YouTube engineers coined the term "the Inversion" to describe this phenomenon. YouTube bots and the fear of "the Inversion" were cited as support for the dead Internet theory in a thread on the Internet forum Melonland. === SocialAI === SocialAI, an app created on September 18, 2024, by Michael Sayman, was created with the full purpose of chatting with only AI bots without human interaction. An article on the Ars Technica website linked SocialAI to the dead Internet theory. === Digg === On June 23, 2025, Alexis Ohanian, one of the Reddit co-founders, said he thought he "long subscribed to the dead Internet

summary:
Fogvid-24 is a social-media conspiracy theory alleging that unusual winter fog in late 2024 and early 2025 was toxic or engineered—variously described as a chemical or biological weapon, "smart dust," or a cover for hidden activity—and that it caused clusters of flu-like symptoms. The term Fogvid-24 was popularised on platforms such as TikTok and X during a period of widespread fog in North America and the United Kingdom. Fact-checkers and meteorologists attributed the reports to ordinary foggy conditions, seasonal respiratory illness, and misinterpretation of visual effects under lights, noting there is no evidence that the fog was engineered or that it contained harmful agents. == Background == In late December 2024, dense fog and freezing fog were widely reported in parts of the United States and the United Kingdom, disrupting transport and prompting routine advisories. During the same period, posts and short videos circulated claiming the fog was unusually thick, smelled "chemical," or left people unwell shortly after exposure; commenters began referring to the phenomenon as Fogvid-24. == Claims == == Responses and expert commentary == Meteorologists and public-health communicators state there is no evidence that the fog was engineered or toxic, and that winter fog is expected under certain

summary:
## [Present, accept, interpret, calculate, repeat](https://developer.mozilla.org/en-US/docs/Games/Anatomy#present_accept_interpret_calculate_repeat) The goal of every video game is to **present** the user(s) with a situation, **accept** their input, **interpret** those signals into actions, and **calculate** a new situation resulting from those acts. Games are constantly looping through these stages, over and over, until some end condition occurs (such as winning, losing, or exiting to go to bed). Not surprisingly, this pattern corresponds to how a game engine is programmed. The specifics depend on the game. Some games drive this cycle by user input. Imagine that you are developing a _"find the differences between these two similar pictures"_ -type game. These games **present** two images to the user; they **accept** their click (or touch); they **interpret** the input as a success, failure, pause, menu interaction, etc.; finally, they **calculate** an updated scene resulting from that input. The game loop is advanced by the user's input and sleeps until they provide it. This is more of a turn-based approach that doesn't demand a constant update every frame, only when the player reacts. Other games demand control over each of the smallest possible individual timeslices. The same principles as above apply with a slight twist: each frame of

summary:
The above sections describe main loops that avoid taking control away from the browser. These main methods attach themselves to `window.requestAnimationFrame()`, which asks the browser for control over the upcoming frame. It is up to the browser how to relate these requests to its main loop. The [HTML spec](https://html.spec.whatwg.org/multipage/imagebitmap-and-animations.html#dom-animationframeprovider-requestanimationframe) does not really define exactly when the browsers must perform the `requestAnimationFrame` callbacks. This can be a benefit because it leaves browser vendors free to experiment with the solutions that they feel are best and tweak them over time. Modern versions of Firefox and Google Chrome (and probably others) _attempt_ to connect `requestAnimationFrame` callbacks to their main thread at the very beginning of a frame's timeslice. The browser's main thread thus _tries_ to look like the following: 1. Start a new frame (while the previous frame is handled by the display). 2. Go through the list of `requestAnimationFrame` callbacks and invoke them. 3. Perform garbage collection and other per-frame tasks when the above callbacks stop controlling the main thread. 4. Sleep (unless an event interrupts the browser's nap) until the monitor is ready for your image ([VSync](https://en.wikipedia.org/wiki/Screen_tearing#Vertical_synchronization)) and repeat.

summary:
You can think about developing realtime applications as having a budget of time to do work. All of the above steps must take place every 16-and-a-half milliseconds to keep up with a 60 Hz display. Browsers invoke your code as early as possible to give it maximum computation time. Your main thread will often start workloads that are not even on the main thread (such as rasterization or shaders in WebGL). Long calculations can be performed on a Web Worker or a GPU at the same time as the browser uses its main thread to manage garbage collection, its other tasks, or handle asynchronous events. While we are on the topic of budgeting time, many web browsers have a tool called _High Resolution Time_. The [`Date`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Date) object is no longer the recognized method for timing events because it is very imprecise and can be modified by the system clock. High Resolution Time, on the other hand, counts the number of milliseconds since `navigationStart` (when the previous document is unloaded). This value is returned as a decimal number accurate to a thousandth of a millisecond. It is known as a [`DOMHighResTimeStamp`](https://developer.mozilla.org/en-US/docs/Web/API/DOMHighResTimeStamp) but, for all intents and purposes, consider it a floating

summary:
### [Other ways to handle variable refresh rate needs](https://developer.mozilla.org/en-US/docs/Games/Anatomy#other_ways_to_handle_variable_refresh_rate_needs) Other methods of tackling the problem exist. One common technique is to update the simulation at a constant frequency and then draw as much (or as little) of the actual frames as possible. The update method can continue looping without care about what the user sees. The draw method can view the last update and when it happened. Since draw knows when it represents, and the simulation time for the last update, it can predict a plausible frame to draw for the user. It does not matter whether this is more frequent than the official update loop (or even less frequent). The update method sets checkpoints and, as frequently as the system allows, the render method draws instants of time around them. There are many ways to separate the update method in web standards: * Draw on `requestAnimationFrame()` and update on a [`setInterval()`](https://developer.mozilla.org/en-US/docs/Web/API/Window/setInterval "setInterval\(\)") or [`setTimeout()`](https://developer.mozilla.org/en-US/docs/Web/API/Window/setTimeout "setTimeout\(\)"). * This uses processor time even when unfocused or minimized, hogs the main thread, and is probably an artifact of traditional game loops (but it is simple.) * Draw on `requestAnimationFrame()` and update on a [`setInterval()`](https://developer.mozilla.org/en-US/docs/Web/API/WorkerGlobalScope/setInterval "setInterval\(\)") or [`setTimeout()`](https://developer.mozilla.org/en-US/docs/Web/API/WorkerGlobalScope/setTimeout "setTimeout\(\)") in a [Web Worker](https://developer.mozilla.org/en-US/docs/Web/API/Web_Workers_API/Using_web_workers).

## [Web technologies for game developers](https://developer.mozilla.org/en-US/docs/Games/Introduction#web_technologies_for_game_developers) For the tech folks, let's dig into the APIs the Web brings to the table that cater to game developers. Here's a thorough list to give you a taste of what the Web can do for you: [Fetch API](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) Send and receive any kind of data you want from a Web server like downloading new game levels and artwork to transmitting non-real-time game status information back and forth. [Full Screen API](https://developer.mozilla.org/en-US/docs/Web/API/Fullscreen_API) This simple API lets your game take over the entire screen, thereby immersing the player in action. [Gamepad API](https://developer.mozilla.org/en-US/docs/Web/API/Gamepad_API/Using_the_Gamepad_API) If you want your users to be able to use gamepads or other game controllers to work your game, you'll need this API. [HTML](https://developer.mozilla.org/en-US/docs/Web/HTML) and [CSS](https://developer.mozilla.org/en-US/docs/Web/CSS) Together, these two technologies let you build, style, and lay out your game's user interface. Part of HTML is the [`<canvas>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/canvas) element, which provides one way to do 2D graphics. [HTML audio](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/audio) The [`<audio>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/audio) element lets you easily play simple sound effects and music. If your needs are more involved, check out the [Web Audio API](https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API) for real audio processing power! [IndexedDB](https://developer.mozilla.org/en-US/docs/Web/API/IndexedDB_API) A powerful data storage API for maintaining user data on their own computer or device. A

## [Benefits of HTML over native](https://developer.mozilla.org/en-US/docs/Games/Publishing_games/Game_distribution#benefits_of_html_over_native) Building games with HTML gives you extra advantages, such as: ### [Multiplatform bliss](https://developer.mozilla.org/en-US/docs/Games/Publishing_games/Game_distribution#multiplatform_bliss) The technology itself is multiplatform, so you can write the code once and target multiple devices. This can range from low-end smartphones or tablets, through laptops and desktop computers, to smart TVs, watches or even a fridge if it can handle a modern enough browser. You don't need to have separate teams to work on the same title targeting different platforms with only one code base to worry about. You can spend more time and money on [Promotion](https://developer.mozilla.org/en-US/docs/Games/Publishing_games/Game_promotion) and [Monetization](https://developer.mozilla.org/en-US/docs/Games/Publishing_games/Game_monetization). ### [Instant updates](https://developer.mozilla.org/en-US/docs/Games/Publishing_games/Game_distribution#instant_updates) You don't have to wait several days to have your game's code updated. If your user finds a bug, you can quickly fix it, update the system and refresh the game on your server to provide players with the updated code almost instantly. ### [Direct link distribution and instant play](https://developer.mozilla.org/en-US/docs/Games/Publishing_games/Game_distribution#direct_link_distribution_and_instant_play) You don't have to tell people to search for your game in an app store with HTML games. You can just send them a direct URL to access the game, which they can then click to play the game right away without the need to use third party

Remember that the name of your game should be unique enough to be quickly [promoted](https://developer.mozilla.org/en-US/docs/Games/Publishing_games/Game_promotion) later on, but also catchy enough, so people don't forget it. ### [Self-hosting](https://developer.mozilla.org/en-US/docs/Games/Publishing_games/Game_distribution#self-hosting) If you are a front-end developer, you may already know what to do. An HTML game is just another website. You can upload it to a remote server, grab a catchy domain name, and host it yourself. If you want to make money out of game dev, you should secure your source code one way or another against people who could easily take it and sell it as their own. You can concatenate and minify the code to make it smaller and uglify it so it's a lot harder to reverse engineer your game. Another good measure to take is to provide an online demo if you're planning on packaging it and selling it in a closed store like iTunes or Steam. If you're working on a side project just for fun, then leaving the source open will benefit those who would like to learn from what you've created. You don't even have to worry about looking for a hosting provider as it's possible to [host games on GitHub Pages](https://end3r.com/blog/host-your-html5-games-on-github-pages). You'll get

If you're looking for more information about the different types of app stores you can check the [List of mobile software distribution platforms](https://en.wikipedia.org/wiki/List_of_mobile_software_distribution_platforms) article on Wikipedia. ### [Native desktop](https://developer.mozilla.org/en-US/docs/Games/Publishing_games/Game_distribution#native_desktop) To broaden your audience you can hit the desktop ecosystem with your HTML games too — just remember all the popular AAA games that take most of the market share, and think carefully about whether this suits your strategy. To do the desktop thing properly you should support all three operating systems: Windows, macOS and Linux. The biggest desktop store for games is definitely [Steam](https://steamcommunity.com/) — indie developers can get on Steam via the [Steam Direct](https://partner.steamgames.com/steamdirect) program. Remember that you have to deal with the cross-platform issues yourself by uploading separate versions for different platforms. After you've covered Steam, there's plenty of buzz around initiatives like [Humble Bundle](https://www.humblebundle.com/) where the most popular indie games get presented to a broader audience. It's more like an excellent promotional opportunity than a way to earn a lot of money, however, as the prices paid for the games in a bundle are usually quite low. ## [Packaging games](https://developer.mozilla.org/en-US/docs/Games/Publishing_games/Game_distribution#packaging_games) The web is the first and the best choice for HTML games, but if you want to

## [Paid games](https://developer.mozilla.org/en-US/docs/Games/Publishing_games/Game_monetization#paid_games) The first, most obvious choice that may come to your mind might be selling the games the way it is done for huge AAA titles — with a fixed, up front price. Even though the digital market is key and you don't need to print covers and put your game in a physical store in boxes, to earn decent money on selling your games for a fixed price you have to invest your time and money in marketing. Only the best games will break even or earn more than they cost to make, and you still need a lot of luck for that. How much you charge for your game depends on the market, quality of your game and a lot of other small factors. An arcade iOS title can be sold for 0.99 USD, but a longer RPG-style desktop game on Steam can cost 20 USD; both prices are OK. You have to follow the market and do your own research — learning from your mistakes quickly is important. ## [In-app purchases](https://developer.mozilla.org/en-US/docs/Games/Publishing_games/Game_monetization#in-app_purchases) Instead of having people pay for your game up front, you can offer a free game with in-app purchases (IAPs.) In this case the

### [Subscriptions](https://developer.mozilla.org/en-US/docs/Games/Publishing_games/Game_monetization#subscriptions) There's also an option to get a passive, monthly revenue via a subscription deal. Instead of getting a one-time payment you can get a small amount of money per game, per month — it can be something around 20-50 USD per month, per game. It's normally up to you if you want to get all the money in a lump sum or get it per month. Remember that it can be cancelled, so it's not an indefinitely working solution. ### [Ad revenue](https://developer.mozilla.org/en-US/docs/Games/Publishing_games/Game_monetization#ad_revenue) You can implement advertisements in your game on your own and try to find the traffic to earn a bit, but you can also do a revenue share deal with a publisher. They will take care of driving the traffic and will split the earnings — usually in a 70/30 or 50/50 deal, collected per month. Remember that many new, low quality publishers will want to get your game for ad revenue instead of licensing because it will be cheaper for them and you might end up with earnings around 2 USD per game for the whole deal. Be careful when dealing with new publishers — sometimes it's better to lower the license cost for a

## [Competitions](https://developer.mozilla.org/en-US/docs/Games/Publishing_games/Game_promotion#competitions) Taking part in competitions will not only level up your gamedev skills and let you meet new devs to befriend and learn from — and it will also get you involved in the community. If you make a good game for a competition and win some prizes in the process your game will automatically be promoted by the organizers and other attendees. You'll be rich and famous, or so they say. Many great games get started as a quick, sloppy demo submitted to a competition. If both the idea and the execution are good enough, you will succeed. Plus competitions generally require games to follow a mandatory theme, so you can get creative around a theme if you are stuck for ideas. ## [Website and blog](https://developer.mozilla.org/en-US/docs/Games/Publishing_games/Game_promotion#website_and_blog) You should definitely create your own website containing all the information about your games, so people can see what you've worked on. The more information you can include the better — you should include screenshots, description, trailer, press kit, requirements, available platforms, support details and more. You'll get bonus points for allowing your users to directly play your games online — at least in demo form. Also, you should do some work

summary:
It's important to focus on the knowledge part and tone down the marketing — devs are sensitive on this matter and you may end up with an angry crowd if you just try to sell them something. ### [Fairs](https://developer.mozilla.org/en-US/docs/Games/Publishing_games/Game_promotion#fairs) The other event-related option is fairs (or expos) — at such an event you can get a booth among other devs and promote your game to all the attendees passing by. If you do so, try to be unique and original, so you easily stand out from the crowd. Do it the right way and everybody will be talking about you and your game. Having a booth gives you the possibility to interact with your fans directly — besides the promotion part, you can also test new builds of your game on regular people and fix any bugs (or incorporate any feedback) they uncover. You can't imagine what people may come up with when playing your game, and what obvious issues you've missed while spending hours polishing it. ## [Promo codes](https://developer.mozilla.org/en-US/docs/Games/Publishing_games/Game_promotion#promo_codes) If you're selling the game, then create the ability to distribute promo codes allowing people to access your game for free (or at least a demo or time-limited version), and

summary:
## [Collision performance](https://developer.mozilla.org/en-US/docs/Games/Techniques/2D_collision_detection#collision_performance) While some of these algorithms for collision detection are simple enough to calculate, it can be a waste of cycles to test _every_ entity with every other entity. Usually games will split collision into two phases, broad and narrow. ### [Broad phase](https://developer.mozilla.org/en-US/docs/Games/Techniques/2D_collision_detection#broad_phase) Broad phase should give you a list of entities that _could_ be colliding. This can be implemented with a spatial data structure that will give you a rough idea of where the entity exists and what exist around it. Some examples of spatial data structures are Quad Trees, R-Trees or a Spatial Hashmap. ### [Narrow phase](https://developer.mozilla.org/en-US/docs/Games/Techniques/2D_collision_detection#narrow_phase) When you have a small list of entities to check you will want to use a narrow phase algorithm (like the ones listed above) to provide a certain answer as to whether there is a collision or not. ## Help improve MDN [Learn how to contribute](https://developer.mozilla.org/en-US/docs/MDN/Community/Getting_started) This page was last modified on May 4, 2026 by [MDN contributors](https://developer.mozilla.org/en-US/docs/Games/Techniques/2D_collision_detection/contributors.txt).

summary:
## [Axis-aligned bounding boxes](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_collision_detection#axis-aligned_bounding_boxes) As with 2D collision detection, **axis-aligned bounding boxes** (AABB) are the quickest algorithm to determine whether the two game entities are overlapping or not. This consists of wrapping game entities in a non-rotated (thus axis-aligned) box and checking the positions of these boxes in the 3D coordinate space to see if they are overlapping. ![Two 3-D non-square objects floating in space encompassed by virtual rectangular boxes.](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_collision_detection/screen_shot_2015-10-16_at_15.11.21.png) The **axis-aligned constraint** is there because of performance reasons. The overlapping area between two non-rotated boxes can be checked with logical comparisons alone, whereas rotated boxes require additional trigonometric operations, which are slower to calculate. If you have entities that will be rotating, you can either modify the dimensions of the bounding box so it still wraps the object, or opt to use another bounding geometry type, such as spheres (which are invariant to rotation.) The animated GIF below shows a graphic example of an AABB that adapts its size to fit the rotating entity. The box constantly changes dimensions to snugly fit the entity contained inside. ![Animated rotating knot showing the virtual rectangular box shrink and grow as the knots rotates within it. The box does not rotate.](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_collision_detection/rotating_knot.gif) **Note:**

This helper takes a `Mesh` and calculates a bounding box volume for it (including its child meshes). This results in a new box `Mesh` representing the bounding box, which shows the bounding box's shape, and can be passed to the previously seen `setFromObject` method in order to have a bounding box matching the `Mesh`. `BoxHelper` is the **recommended** way to handle 3D collisions with bounding volumes in Three.js. You will miss sphere tests, but the tradeoffs are well worth it. The advantages of using this helper are: * It has an `update()` method that will **resize** its bounding box Mesh if the linked Mesh rotates or changes its dimensions, and update its **position**. * It **takes into account the child meshes** when computing the

### [WebXR](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web#webxr) The concept of virtual reality is not new, but it's storming onto the web thanks to hardware advancements such as the [Meta Quest](https://www.meta.com/quest/), and the (currently experimental) [WebXR API](https://developer.mozilla.org/en-US/docs/Web/API/WebXR_Device_API) for capturing information from XR hardware and making it available for use in JavaScript applications. For more, read [WebXR — Virtual and Augmented Reality for the Web](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/WebXR). There's also the [Building up a basic demo with A-Frame](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_A-Frame) article showing you how to build 3D environments for virtual reality using the [A-Frame](https://aframe.io/) framework. ## [The rise of libraries and frameworks](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web#the_rise_of_libraries_and_frameworks) Coding raw WebGL is fairly complex, but you'll want to get to grips with it in the long run, as your projects get more advanced (see our [WebGL documentation](https://developer.mozilla.org/en-US/docs/Web/API/WebGL_API) to get started.) For real-world projects you'll probably also make use of a framework to speed up development and help you manage the project you're working on. Using a framework for 3D games also helps optimize the performance as a lot is taken care of by the tools you use, so you can focus on building the game itself. The most popular JavaScript 3D library is [Three.js](https://threejs.org/), a multipurpose tool that makes common 3D techniques simpler to implement. There are other

summary:
Vertex and fragment processing are programmable — you can [write your own shaders](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/GLSL_Shaders) that manipulate the output. ## [Vertex processing](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Basic_theory#vertex_processing) Vertex processing is about combining the information about individual vertices into primitives and setting their coordinates in the 3D space for the viewer to see. It's like taking a photo of the given scenery you have prepared — you have to place the objects first, configure the camera, and then take the shot. ![Vertex processing](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Basic_theory/mdn-games-3d-vertex-processing.png) There are four stages to this processing: the first one involves arranging the objects in the world, and is called **model transformation**. Then there's **view transformation** which takes care of positioning and setting the orientation of the camera in the 3D space. The camera has three parameters — location, direction, and orientation — which have to be defined for the newly created scene. ![Camera](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Basic_theory/mdn-games-3d-camera.png) **Projection transformation** (also called perspective transformation) then defines the camera settings. It sets up what can be seen by the camera — the configuration includes _field of view_ , _aspect ratio_ and optional _near_ and _far planes_. Read the [Camera paragraph](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_Three.js#camera) in the Three.js article to learn about those. ![Camera settings](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Basic_theory/mdn-games-3d-camera-settings.png) The last step is **viewport transformation** , which involves outputting

summary:
## [High level overview](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_A-Frame#high_level_overview) A-Frame runs on most environments, such as desktop, mobile (iOS and Android), and devices such as Oculus Rift, Gear VR and HTC Vive. A-Frame is built on top of [WebGL](https://developer.mozilla.org/en-US/docs/Web/API/WebGL_API), and provides pre-built components to use in applications — models, video players, skyboxes, geometries, controls, animations, cursors, etc. It is based on the [entity component system](https://en.wikipedia.org/wiki/Entity_component_system), which is known in the game development world, but it targets web developers with a familiar markup structure that can be manipulated with JavaScript. The end result is 3D web experiences, which are VR-enabled by default. ## [Development setup](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_A-Frame#development_setup) To start developing with A-Frame, you should make sure you are using a modern browser with good [WebGL](https://developer.mozilla.org/en-US/docs/Web/API/WebGL_API) support. One option is to set up a VR device such as Oculus Rift or Google Cardboard for the experiments. If you're developing locally in an IDE, make a directory to store your experiments in and save a copy of the [latest A-Frame engine](https://aframe.io/docs/1.6.0/introduction/installation.html) inside that directory. Alternatively, you can load A-Frame from a CDN: Whichever way you choose to get started, make sure you have the [A-Frame documentation](https://aframe.io/docs/) open somewhere while you're working for reference. ### [HTML starter for A-Frame](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_A-Frame#html_starter_for_a-frame) If you're

summary:
### [Specifying a camera](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_A-Frame#specifying_a_camera) A camera entity can be created by adding an [`<a-camera>`](https://aframe.io/docs/primitives/a-camera.html) element to the scene. We can set the position of the camera explicitly and move it back a little bit from the center of the scene, so we'll be able to see the shapes. Add this just before the closing `</a-scene>` tag: We've also defined a cursor for the given camera, using the `cursor-*` attributes (by default it is invisible.) — we've set its scale so it will more easily visible, its color, and some opacity so it won't completely cover the objects behind it. ### [Adding lights](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_A-Frame#adding_lights) The basic light types in A-Frame are directional and ambient. The first type is a directional light placed somewhere on the scene while the second one reflects the light from the first type, so it looks more natural; this can be set globally. Add the new code below your previous additions — this uses the standard `<a-light>` element: The directional light has a white color, its intensity is set to `0.5`, and it is placed at position `-1 1 2`. The ambient light only needs a color, which is also white. ### [Adding some advanced geometry](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_A-Frame#adding_some_advanced_geometry) We have

summary:
## [Development setup](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_Babylon.js#development_setup) To start developing with Babylon.js, you don't need much. Make sure you are using a modern browser with good [WebGL](https://developer.mozilla.org/en-US/docs/Web/API/WebGL_API) support. It's useful to keep the [Babylon.js documentation](https://doc.babylonjs.com/) in a separate tab while you're working. If you're developing locally in an IDE, make a directory to store your experiments in and save a copy of the [latest Babylon.js engine](https://doc.babylonjs.com/setup/frameworkPackages/frameworkVers/) inside that directory. Alternatively, you can load Babylon.js from a CDN: If you don't want to develop locally, you can use an online editor such as [CodePen](https://codepen.io/) or [JSFiddle](https://jsfiddle.net/). With these editors, you can add `https://cdn.babylonjs.com/v7.34.1/babylon.js` as a JavaScript source so it's available in your code. ### [HTML starter for Babylon.js](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_Babylon.js#html_starter_for_babylon.js) If you're building your project locally in an IDE, here's the HTML structure to get started: It contains some basic information like the document [`<title>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/title), and some CSS to set the width and height of the [`<canvas>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/canvas) element (which Babylon.js will use to render the content on) to fill the entire available viewport space. The first [`<script>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/script) element includes the Babylon.js library in the page; we will write our example code in the second one. There is one variable already included, which will store a reference to

It is then positioned to the right of the cube, rotated a bit so its 3D shape can be seen, and given a yellow material. This is good progress, but we can make it more exciting! In a game, something is usually happening — we can see animations and such — so let's try to breathe some life into those shapes by animating them. ## [Animation](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_Babylon.js#animation) We already used `position` and `rotation` to adjust the position of the shapes; we could also scale them. To show actual animation, we need to make changes to these values inside the rendering loop at the end of our code, so they are updated on every frame. Define a helper variable — `t` — that we will use for animations, just before the `renderLoop`, and decrement it on every frame inside the loop, like this: The `t` variable will be incremented on every rendered frame. ### [Rotation](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_Babylon.js#rotation) Applying rotation requires adding this line at the end of the `renderLoop` function: It will rotate the box along the `y` axis. ### [Scaling](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_Babylon.js#scaling) Add this line below the previous one to scale the torus: There's a little bit of adjustment made to make the animation look

![A list of PlayCanvas demos: Tanx, Swooop, Star Lord, BMW i8.](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_PlayCanvas/playcanvas-demos.png) **Note:** Check out the list of [featured demos](https://playcanvas.com/explore) to find more examples. ## [Engine vs. editor](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_PlayCanvas#engine_vs._editor) The engine itself can be used as a standard library by including its JavaScript file directly in your HTML, so you can start coding right away; in addition the PlayCanvas toolset comes with an online editor that you can use to drag and drop components onto the scene — a great way to create games and other apps requiring scenes if you're more of a designer than a coder. Those approaches are different but work equally well regarding achieving end goals. ## [PlayCanvas engine](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_PlayCanvas#playcanvas_engine) Built for modern browsers, PlayCanvas is a fully-featured 3D game engine with resource loading, an entity and component system, advanced graphics manipulation, collision and physics engine (built with [ammo.js](https://github.com/kripken/ammo.js/)), audio, and facilities to handle control inputs from various devices (including gamepads). That's quite an impressive list of features — let's see some in action, check out the [Building up a basic demo with PlayCanvas engine](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_PlayCanvas/engine) for details. ## [PlayCanvas editor](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_PlayCanvas#playcanvas_editor) Instead of coding everything from the beginning you can also use the online editor.

![PlayCanvas Editor - New project](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_PlayCanvas/editor/playcanvas-editor-newproject.png) Next you'll see your project's page — there's not much yet. By clicking the _Editor_ button we'll launch the online PlayCanvas editor where we'll create our scene with the shapes. Do this now. ![PlayCanvas Editor - Project](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_PlayCanvas/editor/playcanvas-editor-project.png) ## [Creating the scene](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_PlayCanvas/editor#creating_the_scene) Here's how the scene looks initially in the editor. Even though it's a blank new project we don't have to start entirely from scratch — the camera and directional light are prepared already, so you don't have to worry about them. ![PlayCanvas Editor - Scene](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_PlayCanvas/editor/playcanvas-editor-scene.png) Now onto the creative part. To add an entity to the scene you have to click on the big plus button located in the top left area of the editor, next to the Hierarchy text. When hovering over that button with your mouse the label will say 'Add Entity' — that's exactly what we want to do. An Entity is any object used in the scene — it can be an object like a box, cylinder or cone, but it can also be a camera, light or sound source. After clicking the button you'll see a dropdown list containing a lot of various entities to choose from. Go ahead

![PlayCanvas Editor - Cylinder material](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_PlayCanvas/editor/playcanvas-editor-cylindermaterial.png) Follow the same approach again to add a cone to the scene, giving it a grayish color (we used `#EAEFF2`.) You should now have three shapes on your scene, something like the below screenshot. ![PlayCanvas Editor - Cone](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_PlayCanvas/editor/playcanvas-editor-cone.png) ## [Animating our scene](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_PlayCanvas/editor#animating_our_scene) Animating 3D models might be considered an [advanced](https://developer.playcanvas.com/en/tutorials/anim-blending/) thing to do, but all we want to do is to control a few properties of a given object — we can use a script component to do that. Click on the plus button in the Assets panel, select the Script option, and name your new script file `boxAnimation.js`. ![PlayCanvas Editor - Box animation](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_PlayCanvas/editor/playcanvas-editor-boxanimation.png) If you double click on it, you'll be moved to a code editor. As you can see, the file contains some boilerplate code already: The most interesting part is the `update()` function, which is where we can put any code that we want repeated on every frame. Add the following line inside this function, to rotate the cube on every frame: In the line above `this.entity` refers to the object to which the script will be attached (the box); using the `dt` variable, which contains the delta time passed since the

summary:
## [Development setup](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_PlayCanvas/engine#development_setup) To start developing with PlayCanvas, make sure you are using a modern browser with good [WebGL](https://developer.mozilla.org/en-US/docs/Web/API/WebGL_API) support. It's useful to keep the [PlayCanvas documentation](https://developer.playcanvas.com/en/user-manual/) in a separate tab while you're working. If you're developing locally in an IDE, make a directory to store your experiments in and save a copy of the [latest PlayCanvas engine](https://code.playcanvas.com/playcanvas-latest.js) inside that directory. Alternatively, you can load PlayCanvas from a CDN: If you don't want to develop locally, you can use an online editor such as [CodePen](https://codepen.io/) or [JSFiddle](https://jsfiddle.net/). With these editors, you can add `https://cdn.babylonjs.com/babylon.js` as a JavaScript source so it's available in your code. ### [HTML starter for PlayCanvas](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_PlayCanvas/engine#html_starter_for_playcanvas) If you're building your project locally in an IDE, here's the HTML structure to get started: It contains information like the document [`<title>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/title), and some CSS to set the width and height of the [`<canvas>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/canvas) element (that PlayCanvas will use) to 100%, so that it will fill the entire available viewport space. The first [`<script>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/script) element includes the PlayCanvas library in the page; we will write our example code in the second one. There is one variable already included, which will store a reference to the [`<canvas>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/canvas) element. If you're developing

summary:
In a game something is usually happening — we can see animations and such — so let's try to breathe a little life into those shapes by animating them. ## [Animation](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_PlayCanvas/engine#animation) We already used `translate` or `rotate` to adjust the position of the shapes; we could also change their positions directly with `setPosition`, or scale them. To show actual animation, we need to make changes to these values inside the rendering loop, so they are updated on every frame. There's a special `update` event that we can use for that — add the following code just below the previous additions: The callback takes the `deltaTime` as the parameter, so we have the relative time that has passed since the previous invocation of this update. For time based animations we'll use a `timer` variable that will store the time that has passed since the start of the app by adding the `deltaTime` to it on every update. ### [Rotation](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_PlayCanvas/engine#rotation) Rotating is quite easy — all you need to do is to add a defined value to the given direction of rotation on each frame. Add this line of code inside the `app.on("update")` callback function, right after the addition of the `deltaTime`

summary:
## [Development setup](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_Three.js#development_setup) To start developing with Three.js, you should make sure you are using a modern browser with good [WebGL](https://developer.mozilla.org/en-US/docs/Web/API/WebGL_API) support. In your code, you can import Three.js [using a CDN or use Node.js](https://threejs.org/docs/#manual/en/introduction/Installation). If you're including it from a CDN, you can use the following URL in your HTML: A Node.js setup with Three.js installed as a dependency is convenient if you want to develop against specific Three.js versions and it can speed up collaboration and deployment: Alternatively, you can download the [latest Three.js library](https://github.com/mrdoob/three.js/archive/master.zip) and copy the minified version of Three.js from the uncompressed archive at `build/three.module.min.js` into your project. Bear in mind that the archives include source files, which makes the download size approximately 350MB. Whichever way you choose to get started, make sure you have the [Three.js documentation](https://threejs.org/docs/) open somewhere while you're working for reference. ### [HTML starter for Three.js](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_Three.js#html_starter_for_three.js) If you're building your project locally in an IDE, here's the HTML structure to get started: It contains some basic information like the document [`<title>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/title), and some CSS to set the `width` and `height` of the [`<canvas>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/canvas) element, that Three.js will insert on the page to 100% to fill the entire available viewport space.

summary:
You should experiment with these values and see how they change what you see in the scene. The distance values (e.g., for the camera z position) are unitless, and can be anything you deem suitable for your scene: millimeters, meters, feet, or miles. It's up to you. ## [Rendering the scene](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_Three.js#rendering_the_scene) Everything is ready, but we still can't see anything. Although we've set up the renderer, we still need to render everything. Our `render()` function will do this job, with a little help from [`requestAnimationFrame()`](https://developer.mozilla.org/en-US/docs/Web/API/Window/requestAnimationFrame), which causes the scene to be re-rendered constantly on every frame: On every new frame the `render` function is invoked, and the `renderer` renders the `scene` and the `camera`. Right after the function declaration, we're invoking it for the first time to start the loop, after which it will be used indefinitely. Again, add this new code below your previous additions. Try saving the file and opening it in your browser. You should now see a gray window. Congratulations! ## [Geometry](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_Three.js#geometry) Now our scene is properly rendering, we can start adding 3D shapes. To speed up development, Three.js provides a bunch of predefined primitives, which you can use to create shapes instantly in a single

Add the following, again just below our `requestAnimationFrame()` invocation: This will move the dodecahedron up and down by applying the `sin()` value to the y-axis on each frame, and a little adjustment to make it look cooler. Try changing these values, to see how it affects the animations. ## [Three.js example with animation](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_Three.js#three.js_example_with_animation) Here's the final code with animated shapes.

You can continue reading the [3D Games on the Web](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web) documentation if you want to learn more. You could also try learning WebGL, to gain a better understanding of what's going on underneath.

summary:
## [Shader types](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/GLSL_Shaders#shader_types) A shader is essentially a function required to draw something on the screen. Shaders run on a [GPU](https://en.wikipedia.org/wiki/GPU) (graphics processing unit), which is optimized for such operations. Using a GPU to deal with shaders offloads some of the number crunching from the CPU. This allows the CPU to focus its processing power on other tasks, like executing code. ### [Vertex shaders](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/GLSL_Shaders#vertex_shaders) Vertex shaders manipulate coordinates in a 3D space and are called once per vertex. The purpose of the vertex shader is to set up the `gl_Position` variable — this is a special, global, and built-in GLSL variable. `gl_Position` is used to store the position of the current vertex. The `void main()` function is a standard way of defining the `gl_Position` variable. Everything inside `void main()` will be executed by the vertex shader. A vertex shader yields a variable containing how to project a vertex's position in 3D space onto a 2D screen. ### [Fragment shaders](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/GLSL_Shaders#fragment_shaders) Fragment (or texture) shaders define RGBA (red, green, blue, alpha) colors for each pixel being processed — a single fragment shader is called once per pixel. The purpose of the fragment shader is to set up the `gl_FragColor` variable. `gl_FragColor` is

Before reading on, copy this code to a new text file and save it in your working directory as `index.html`. We'll create a scene featuring a simple cube in this file to explain how the shaders work. ### [The cube's source code](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/GLSL_Shaders#the_cubes_source_code) Instead of creating everything from scratch we can reuse the [Building up a basic demo with Three.js](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/Building_up_a_basic_demo_with_Three.js) source code of the cube. Most of the components like the renderer, camera, and lights will stay the same, but instead of the basic material we will set the cube's color and position using shaders. Go to the [cube.html file on GitHub](https://github.com/end3r/MDN-Games-3D/blob/gh-pages/Three.js/cube.html), copy all the JavaScript code from inside the second [`<script>`](https://developer.mozilla.org/en-US/docs/Web/HTML/Reference/Elements/script) element, and paste it into the third `<script>` element of the current example. Save and load `index.html` in your browser — you should see a blue cube. ### [The vertex shader code](https://developer.mozilla.org/en-US/docs/Games/Techniques/3D_on_the_web/GLSL_Shaders#the_vertex_shader_code) Let's continue by writing a simple vertex shader — add the code below inside the body's first `<script>` tag: The resulting `gl_Position` is calculated by multiplying the model-view and the projection matrices by each vector to get the final vertex position, in each case. **Note:** You can learn more about _model_ , _view_ , and _projection transformations_

summary:
Many browsers will ignore any requests made by your game to automatically play audio; instead playback for audio needs to be started by a user-initiated event, such as a click or tap. This means you will have to structure your audio playback to take account of that. This is usually mitigated against by loading the audio in advance and priming it on a user-initiated event. For more passive audio autoplay, for example background music that starts as soon as a game loads, one trick is to detect _any_ user initiated event and start playback then. For other more active sounds that are to be used during the game we could consider priming them as soon as something like a _Start_ button is pressed. To prime audio like this we want to play a part of it; for this reason it is useful to include a moment of silence at the end of your audio sample. Jumping to, playing, and then pausing that silence will mean we can now use JavaScript to play that file at arbitrary points. You can find out more about [best practices with the autoplay policy here](https://developer.mozilla.org/en-US/docs/Web/API/Web_Audio_API/Best_practices#autoplay_policy). **Note:** Playing part of your file at zero volume could

summary:
This is often the way that musicians compose music anyway, and the Web Audio API is extremely good at keeping these parts in sync. Once you have the various tracks that make up your piece you can bring tracks in and out as appropriate. You can also apply filters or effects to music. Is your character in a cave? Increase the echo. Maybe you have underwater scenes, during which you could apply a filter that muffles the sound. Let's look at some Web Audio API techniques for dynamically adjusting music from its base tracks. ### [Loading your tracks](https://developer.mozilla.org/en-US/docs/Games/Techniques/Audio_for_Web_Games#loading_your_tracks) With the Web Audio API you can load separate tracks and loops individually using the [Fetch API](https://developer.mozilla.org/en-US/docs/Web/API/Fetch_API) or [`XMLHttpRequest`](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest), which means you can load them synchronously or in parallel. Loading synchronously might mean parts of your music are ready earlier and you can start playing them while others load. Either way you may want to synchronize tracks or loops. The Web Audio API contains the notion of an internal clock that starts ticking the moment you create an audio context. You'll need to take account of the time between creating an audio context and when the first audio track starts playing. Recording

summary:
## [Case study](https://developer.mozilla.org/en-US/docs/Games/Techniques/Control_mechanisms#case_study) We'll be using the [Captain Rogers: Battle at Andromeda demo](https://rogers2.enclavegames.com/demo/) as an example. ![Captain Rogers: Battle at Andromeda - cover of the game containing Enclave Games and Blackmoon Design logos, Roger's space ship and title of the game.](https://developer.mozilla.org/en-US/docs/Games/Techniques/Control_mechanisms/captainrogers2-cover.png) Captain Rogers was created using the [Phaser](https://phaser.io/) framework, the most popular tool for simple 2D game development in JavaScript right now, but it should be fairly easy to reuse the knowledge contained within these articles when building games in pure JavaScript or any other framework. If you're looking for a good introduction to Phaser, then check the [2D breakout game using Phaser](https://developer.mozilla.org/en-US/docs/Games/Tutorials/2D_breakout_game_Phaser) tutorial. In the following articles we will show how to implement various different control mechanisms for Captain Rogers to support different platforms — from touch on mobile, through keyboard/mouse/gamepad on desktop, to more unconventional ones like TV remote, shouting to or waving your hand in front of the laptop, or squeezing bananas. ## [Setting up the environment](https://developer.mozilla.org/en-US/docs/Games/Techniques/Control_mechanisms#setting_up_the_environment) Let's start with a quick overview of the game's folder structure, JavaScript files and in-game states, so we know what's happening where. The game's folders look like this: ![Captain Rogers: Battle at Andromeda - folder structure of the games' project

## [API status, browser and hardware support](https://developer.mozilla.org/en-US/docs/Games/Techniques/Control_mechanisms/Desktop_with_gamepad#api_status_browser_and_hardware_support) The [Gamepad API](https://developer.mozilla.org/en-US/docs/Web/API/Gamepad_API) is still in Working Draft status, although browser support is already quite good — around 63% global coverage, according to [caniuse.com](https://caniuse.com/#search=gamepad). The list of supported devices is also quite extensive — most popular gamepads (e.g., XBox 360 or PS3) should be suitable for web implementations. ## [Pure JavaScript approach](https://developer.mozilla.org/en-US/docs/Games/Techniques/Control_mechanisms/Desktop_with_gamepad#pure_javascript_approach) Let's think about implementing pure JavaScript gamepad controls in our [little controls demo](https://github.com/end3r/JavaScript-Game-Controls/) first to see how it would work. First, we need an event listener to listen for the connection of the new device: It's executed once, so we can create some variables we will need later on for storing the controller info and the pressed buttons: The second line in the `gamepadHandler` function shows up on the screen when the device is connected: ![Gamepad connected message under the Captain Rogers game - wireless XBox 360 controller.](https://developer.mozilla.org/en-US/docs/Games/Techniques/Control_mechanisms/Desktop_with_gamepad/controls-gamepadtext.png) We can also show the `id` of the device — in the case above we're using the XBox 360 wireless controller. To update the state of the gamepad's currently pressed buttons we will need a function that will do exactly that on every frame: We first reset the `buttonsPressed` array to get it

summary:
Have you noticed that the current value of the axes is evaluated against `0.5`? It's because axes are having floating point values while buttons are booleans. After a certain threshold is reached we can assume the input is done deliberately by the user and can act accordingly. For the shooting controls, we used the `A` button — when it is held down, a new bullet is spawned, and everything else is handled by the game: Showing the screen with all the controls looks exactly the same as in the main menu: If the `B` button is pressed, the game is paused: ## [The paused and game-over states](https://developer.mozilla.org/en-US/docs/Games/Techniques/Control_mechanisms/Desktop_with_gamepad#the_paused_and_game-over_states) We already learned how to control the whole lifecycle of the game: pausing the gameplay, restarting it, or getting back to the main menu. It works smooth on mobile and desktop, and adding gamepad controls is just as straightforward — in the `update()` function, we check to see if the current state status is "paused" — if so, the relevant actions are enabled: Similarly, when the "game-over" state status is active, then we can allow the user to restart the game instead of continuing it: When the game over screen is visible, the

summary:
## [Pure JavaScript approach](https://developer.mozilla.org/en-US/docs/Games/Techniques/Control_mechanisms/Desktop_with_mouse_and_keyboard#pure_javascript_approach) Let's think about implementing pure JavaScript keyboard/mouse controls in the game first, to see how it would work. First, we'd need an event listener to listen for the pressed keys: Whenever any key is pressed down, we're executing the `keyDownHandler` function, and when press finishes we're executing the `keyUpHandler` function, so we know when it's no longer pressed. To do that, we'll hold the information on whether the keys we are interested in are pressed or not: Then we will listen for the `keydown` and `keyup` events and act accordingly in both handler functions. Inside them we can get the code of the key that was pressed from the [`code`](https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/code) property of the event object, see which key it is, and then set the proper variable. The codes are all readable string names, but you can [look them up](https://developer.mozilla.org/en-US/docs/Web/API/UI_Events/Keyboard_event_code_values) to be sure; `"ArrowLeft"` is the left arrow: The `keyUpHandler` looks almost exactly the same as the `keyDownHandler` above, but instead of setting the pressed variables to `true`, we would set them to `false`. If the left arrow is pressed (`⬅︎`; `"ArrowLeft"`), we can set the `leftPressed` variable to `true` and in the `draw` function perform the

For example, by specifying `Phaser.KeyCode.Backspace` or `Phaser.KeyCode.Delete` you can hook up an action to fire when the `Delete/Backspace` button is pressed. ## [Summary](https://developer.mozilla.org/en-US/docs/Games/Techniques/Control_mechanisms/Desktop_with_mouse_and_keyboard#summary) Ok, we've dealt with touch, keyboard, and mouse controls. Now let's move on to look at how to set up the game to be controlled using a console gamepad, using the [Gamepad API](https://developer.mozilla.org/en-US/docs/Web/API/Gamepad_API). * [ Previous ](https://developer.mozilla.org/en-US/docs/Games/Techniques/Control_mechanisms/Mobile_touch) * [ Overview: Implementing game control mechanisms](https://developer.mozilla.org/en-US/docs/Games/Techniques/Control_mechanisms) * [ Next ](https://developer.mozilla.org/en-US/docs/Games/Techniques/Control_mechanisms/Desktop_with_gamepad)

**Note:** The [touch events](https://developer.mozilla.org/en-US/docs/Web/API/Touch_events) reference article provides more examples and information. ### [Pure JavaScript demo](https://developer.mozilla.org/en-US/docs/Games/Techniques/Control_mechanisms/Mobile_touch#pure_javascript_demo) Let's implement the mobile support in a [little demo](https://github.com/end3r/JavaScript-Game-Controls/) available on GitHub, so we can move the player's ship by touching the screen on a mobile device. We will use two events: `touchstart` and `touchmove`, both handled by one function. Why? The function `touchHandler` will assign proper variables to the ship's position so that we can use it for both cases: when the player touches the screen but doesn't move it (`touchstart`), and when the finger is moved on the screen (`touchmove`): The `touchHandler` function looks like this: If the touch occurs (`touches` object is not empty), then we will have all the info we need in that object. We can get the first touch (`e.touches[0]`, our example is not multitouch-enabled), extract the `pageX` and `pageY` variables and set the player's ship position on the screen by subtracting the Canvas offset (distance from the Canvas and the edge of the screen) and half the player's width and height. ![Touch controls for the player's ship, with visible output of the x and y position.](https://developer.mozilla.org/en-US/docs/Games/Techniques/Control_mechanisms/Mobile_touch/controls-touch.png) To see if it's working correctly we can output the `x` and

## [TV remote](https://developer.mozilla.org/en-US/docs/Games/Techniques/Control_mechanisms/Other#tv_remote) Playing games on a TV screen doesn't always have to be done through consoles. There's already a Gamepad API working on the desktop computers, so we can imitate the experience, but we can go even further. Modern smart TVs can handle HTML games, because they have a built-in browser that can be used as a gaming platform. Smart TVs are shipped with remote controls, which can be used to control your games if you know how. The earliest demo of [Captain Rogers: Battle at Andromeda](https://rogers2.enclavegames.com/demo/) was adjusted to work on a huge TV. Interestingly enough, the first Captain Rogers game (Asteroid Belt of Sirius) was optimized for low-end, small-screen, cheap smartphones running Firefox OS, so you can see the difference three years can make — you can read the whole story in our [Building games for Firefox OS TV](https://hacks.mozilla.org/2016/01/building-games-for-firefox-os-tv/) Hacks post. ![Panasonic TV remote controls for the game Captain Rogers: Battle at Andromeda.](https://developer.mozilla.org/en-US/docs/Games/Techniques/Control_mechanisms/Other/controls-tvremote.png) Using a TV remote to control the game ended up being surprisingly easy, because the events fired by the controller are emulating conventional keyboard keys. Captain Rogers had the keyboard controls implemented already: It works out of the box. The cursors are the four

summary:
## [Controls for web games](https://developer.mozilla.org/en-US/docs/Games/Techniques/Controls_Gamepad_API#controls_for_web_games) Historically playing games on a console connected to your TV was always a totally different experience to gaming on the PC, mostly because of the unique controls. Eventually, extra drivers and plugins allowed us to use console gamepads with desktop games — either native games or those running in the browser. Now we have the [Gamepad API](https://developer.mozilla.org/en-US/docs/Web/API/Gamepad_API), which gives us the ability to play browser-based games using gamepad controllers without any plugins. The Gamepad API achieves this by providing an interface exposing button presses and axis changes that can be used inside JavaScript code to handle the input. These are good times for browser gaming. ## [Which gamepads are best?](https://developer.mozilla.org/en-US/docs/Games/Techniques/Controls_Gamepad_API#which_gamepads_are_best) The most popular gamepads right now are those from the Xbox 360, Xbox One, PS3 and PS4 — they have been heavily tested and work well with the Gamepad API implementation in browsers across Windows and macOS. There's also a number of other devices with various different button layouts that more or less work across browser implementations. The code discussed in this article was tested with a few gamepads, but the author's favorite configuration is a wireless Xbox 360 controller and the Firefox browser on

summary:
The `index` variable is useful if we're connecting more than one controller and want to identify them to act accordingly — for example when we have a two-player game requiring two devices to be connected. ### [Querying the gamepad object](https://developer.mozilla.org/en-US/docs/Games/Techniques/Controls_Gamepad_API#querying_the_gamepad_object) Beside `connect()` and `disconnect()`, there are two more methods in the `gamepadAPI` object: `update()` and `buttonPressed()`. `update()` is executed on every frame inside the game loop, to update the actual status of the gamepad object regularly: On every frame, `update()` saves buttons pressed during the previous frame to the `buttonsCache` array and takes fresh ones from the `gamepadAPI.controller` object. Then it loops through buttons and axes to get their actual states and values. ### [Detecting button presses](https://developer.mozilla.org/en-US/docs/Games/Techniques/Controls_Gamepad_API#detecting_button_presses) The `buttonPressed()` method is also placed in the main game loop to listen for button presses. It takes two parameters — the button we want to listen to and the (optional) way to tell the game that holding the button is accepted. Without it you'd have to release the button and press it again to have the desired effect. There are two types of action to consider for a button: a single press and a hold. The `newPress` boolean variable will indicate whether

summary:
## [The concept](https://developer.mozilla.org/en-US/docs/Games/Techniques/Crisp_pixel_art_look#the_concept) Retro [pixel art](https://en.wikipedia.org/wiki/Pixel_art) aesthetics are getting popular, especially in [indie games](https://en.wikipedia.org/wiki/Indie_game) or [game jam](https://en.wikipedia.org/wiki/Game_jam) entries. But since today's screens render content at high resolutions, there is a problem with making sure the pixel art does not look blurry. Here's an original image that an actual arcade game may have used: ![small pixelated man](https://developer.mozilla.org/en-US/docs/Games/Techniques/Crisp_pixel_art_look/technique_original.png) We can manually scale it up in an image editor, expanding each pixel into a 4x4 block of pixels. The image editor can leverage algorithms like [nearest-neighbor interpolation](https://en.wikipedia.org/wiki/Nearest-neighbor_interpolation) to achieve crisp edges. ![larger pixelated man](https://developer.mozilla.org/en-US/docs/Games/Techniques/Crisp_pixel_art_look/technique_4x.png) Two downsides to this method are larger file sizes and [compression artifacts](https://en.wikipedia.org/wiki/Compression_artifact), because the image actually contains more pixels. The idea of producing crisp pixel art is simple: we want to have a single pixel in the original image map to a block of pixels on the screen, without any smoothing or blending between them. The example above achieves this by manually doing that mapping in an image editor. But we can also achieve this effect in the browser using CSS. ## [Up-scaling <img> with CSS](https://developer.mozilla.org/en-US/docs/Games/Techniques/Crisp_pixel_art_look#up-scaling_img_with_css) An image has an intrinsic size, which is its actual pixel dimensions. It also has a rendered size, which is set by HTML

summary:
Let's have a look at an example. The original image we want to upscale looks like this: ![Pixelated night scenery of a cat on the edge off a cliff with little hearts above his head, behind him a big full moon. With a black background, white text is displayed at the bottom of the image saying: in love with the moon.](https://developer.mozilla.org/en-US/docs/Games/Techniques/Crisp_pixel_art_look/cat.png) Here's some HTML to create a simple canvas: CSS to size the canvas and render a crisp image: And some JavaScript to set up the canvas and load the image: This code used together produces the following result: **Note:** Canvas content is not accessible to screen readers. Include descriptive text as the value of the [`aria-label`](https://developer.mozilla.org/en-US/docs/Web/Accessibility/ARIA/Reference/Attributes/aria-label) attribute directly on the canvas element itself or include fallback content placed within the opening and closing canvas tag. Canvas content is not part of the DOM, but nested fallback content is. ## [Arbitrarily scaling images in canvas](https://developer.mozilla.org/en-US/docs/Games/Techniques/Crisp_pixel_art_look#arbitrarily_scaling_images_in_canvas) For the character example with a plain `<img>`, you can set the scale factor to any value you want, and `image-rendering: pixelated` will do its best to preserve crisp edges. For example, you can scale the image by 5.7x: ![small pixelated man, upscaled with CSS,

summary:
### [Static tilemaps](https://developer.mozilla.org/en-US/docs/Games/Techniques/Tilemaps#static_tilemaps) A tilemap can either fit into the visible screen area screen or be larger. In the first case, the tilemap is **static** — it doesn't need to be scrolled to be fully shown. This case is very common in arcade games like _Pacman_ , _Arkanoid_ , or _Sokoban_. Rendering static tilemaps is easy, and can be done with a nested loop iterating over columns and rows. A high-level algorithm could be: You can read more about this and see an example implementation in [Square tilemaps implementation: Static maps](https://developer.mozilla.org/en-US/docs/Games/Techniques/Tilemaps/Square_tilemaps_implementation:_Static_maps). ### [Scrolling tilemaps](https://developer.mozilla.org/en-US/docs/Games/Techniques/Tilemaps#scrolling_tilemaps) **Scrolling** tilemaps only show a small portion of the world at a time. They can follow a character — like in platformers or RPGs — or allow the player to control the camera — like in strategy or simulation games. #### Positioning and camera In all scrolling games, we need a translation between **world coordinates** (the position where sprites or other elements are located in the level or game world) and **screen coordinates** (the actual position where those elements are rendered on the screen). The world coordinates can be expressed in terms of tile position (row and column of the map) or in pixels across the
